I personally didn't like the Freeze story arc. It was boring, predictable and uneventful IMO; this show has kept me interested because of its unpredictable nature. Hugo Strange has been underwhelming thus far IMO, but there's definitely room for growth.
Boy, I did not expect the plot twist with Gordon at all. Hopefully no more sub plots for the rest of the season. Please continue to develop the main plot points with Gordon, Penguin, Riddler, Bruce, etc. Save the sub plots for next season, there's enough going on already. During the Galavan story arc, I felt like there was too much going on for 42 minutes. Just got renewed for a third season and I think this show will air as long as they want, it does very well in ratings (especially for Fox). No need to keep forcing in new characters and plot lines. Take your time, Gotham.

I'm guessing we'll be hearing from Barbara again soon....
They've been heavy promoting her on their Twitter page and tonight there's no new episode (I assume not to conflict with Natl Champ), but they're re-airing the episode with the wedding from a few months back.....
With Lee out of the picture atm and the miscarriage, this opens the door back up for Barbara. We saw what Hugo did to Penguin, I assume he'll do the same to Barbara.
Plus, we know Fish is coming back. I wouldn't be surprised if she comes back Monday and helps Jim possibly...her and Harvey were close friends....
